00:02
100 sample of the tulip plant parts are placed in four different sealed containers and i label them as 1, 2, 3, 4.
00:10
So they have equal volume and size.
00:13
Each container was exposed to different temperature for several days.
00:16
And of course, you have different parts in each container.
00:19
You have 1 and 4 having flowers in it and 2 and 3 have leaves in it.
00:25
So the amount of carbon dioxide co2 present in each of the container are at the beginning of the experiment was, all 200 milliter.
00:35
After two days, the carbon dioxide level were measured again.
00:40
Those levels were showing in the last column, we called a final carbon dioxide.
00:45
So the question asked you to write an argument that explain whether or not the photo synthesis is impacted by plant parts or temperature, assuming that the testing condition that are not listed are identical in all four containers.
01:00
And then, obviously, the tests were repeated five times.
01:04
So a is photosynthesis affected by plant part or temperature? so the claim is the rate of photosynthesis is affected by both the plant part and temperature.
01:57
So to be specific, as you can see, if you check the initial volume of the co2, and the final volume of co2, you can tell that the flower container does not have a decrease in carbon dioxide level.
02:18
But the leaf obviously has a decreased amount of carbon dioxide level, which means the photosynthesis only occurs in leaf.
02:33
Photo synthethyst only occurs in the leaf of the tulip.
03:02
The first statement, second, if you compare the temperature, so look at container number two and three, you can tell that temperature goes from 15 to 27, and then the initial co2 level are the same.
03:19
However, you have a lower co2 final level at 27 degrees celsius.
03:26
So this means more carbon dioxide is consumed into container number three.
03:32
So this means a higher photosynthesis rate occurs at a higher temperature.
03:42
Higher temperature causes a higher rate of photosynthesis.
04:05
All right, so this is the first question.
04:15
What data from a table help you to come to the conclusion? evidence.
04:21
So let's look at number one statement that photosynthesis only occurs in the leaf of the tulip.
04:30
So if you look at container number one and four, which has flowers, the volume of carbon dioxide did not decrease.
04:58
So that means there was no consumption of carbon dioxide.
05:21
So this is the major data to support that flour do not carry out photosynthes because during photosynthesis carbon dioxide is being used to synthesize chemical energy, which is glucose.
05:38
So if photosynthesis happens, the amount of of carbon dioxide will decrease because it will be consumed by phototentitis.
05:47
Now in both container 1 and 4, when you have flowers in it, the amount of co2 either increases or does not increase at all.
05:57
So this means there's no consumption of co2, there's no phototenditis.
06:02
So i summarize my answer here.
06:04
Container 1 in 4 with flowers and the volume of co2 did not decrease.
06:09
There is no consumption of carbon dioxide and obviously no photosynthesis occurred in flour.
06:31
Also, let's look at the second statement that the higher temperature cause a higher rate of photothynthesies...
